Zusammenfassung:	PURPOSE:To prepare a vehicle for a printing ink having excellent heat resistance by condensation-polymerizing a particular polyamine component with a particular aliph. monocarboxylic acid component and a particular polyhydric carboxylic acid component. CONSTITUTION:A polyamine component (A) of the formula (wherein R is a 2-3C alkylene; and n is 1-5) (e.g., ethylenediamine or diethylenetriamine) is condensation-polymerized with an OH group-contg. 3-22C aliph. monocarboxylic acid component (B) (e.g., 2-hydroxypropionic acid), 16-100wt.% polybasic carboxylic acid component mainly composed of a polymerized fatty acid (e.g., one comprising 0-5wt.% 18C monobasic acid; 16-100wt.% 36C dibasic acid, and 0-30wt.% 54C tribasic or higher acid) under such conditions that the acid equivalent of B component/the acid equivalent of C component is 0.05-1.0 and the amt. of the polyamine component is substantially equivalent to the amt. of the carboxylic acid component. Thus, there is obtd. a vehicle for a printing ink having excellent heat resistance which comprises a polyamide resin for gravure ink useful for printing of a plastic film.
